1'1 Claims.

This invention relates to window constructions, particularly window structures for buses, railway cars, and the like, and has for its object a particularly simple and economical window construction or assembly embodying sash guide members which are automatically adjustable in a direction edgewise of the window structure to compensate'for misalinements, within limits, of the window frame or the sash or both and. for variations in the widths of standard sized sashes without applying to the sash, during its sliding. or opening and closing movement, a braking effect, but at the same time holding the sash from looseness and rattling, all whereby the sash lid t In this type of window, the spring-pressedguidemember,,-ha s a marked braking or brake-shoe effect on" the sash andthe operation of the sash, during its raising and lowering, is constantly varying under difierent atmospheric conditions. Another type is shown in Are Patent No. 1,97%,63'7 issued September 25, 1934 in which the guide .member, after being adjusted to compensate for misalinements, etc. is firmly clamped in its adjusted position. See also Axe Patent No. 1,922,010 issued August 8, 1933. Another class is that shown in the application of Oliver M, Edwards, serial Number 15,649, filed April 10, 1935 in which springs are employed to automatically effect the adjustment in contradistinction to manipulating the guide members to their adjusted position, and in which the guide member, after the springs have automatically ad iusted it, is clamped in position to relieve the guide member of the spring pressure, so that the guide member does not have a varying brakeshoe effect on the sash during raising and lowering thereof.

The object of this invention is a window stru, ture which has all of the advantages and none of the disadvantages of the three types above referred to, that is, the sash guide is automatically adjusted by a cushion acting uniformly on the guide member throughout the length thereof instead of localizing the pressure at spaced apart I points, so that the guide member does not exert a brake-shoe action and yet is not clamped in its adjusted position but is free to, at all times, adjust itsell edgewise relative to the sash.

Another object of the invention is a window structure in which the sash and the guide member have slidably interfitting tongue and groove means with a non-metallic weather strip in the groove and coacting with the tongue to hold the sash and the guide out of metal to metal contact, together with means for holding or preventing the tongue of said means from wearing the nonmetallic weather strip, where it thrusts against the same. It will be understood that the sash and sash guides are usually formed of metal.

The invention'consists in the novel features and iii in the combinations and constructions hereinafter set forth and cled.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 7 is a view similar. to Figure 3 illustrating a modified form of the invention.

Figure 8 is asectional view, similar to Figure 3, illustrating my invention as applied to a different form of post structure from that shown in Figure 3.

l designates the window frame which includes post structures 2 between the windows or at the sides of a single window. 5 designates the sash, this being capable of being raised and lowered. 4 is an upper stationary sash with which bus windows are usually provided. The stationary here shown as mounted in a channel member 6 applied to the post structure 2, and usually one side of the channel 6 is demountable for the purpose of removing and replacing the sash or the guide member. The demountable side comprises a plate I which is clamped to the post structure by screws 8, and forms a facing or trim for the post structure on the interior of the car body. For the intermediate posts, the plate I is formed double and coacts with the guide members 5 on both sides of the post.

The guide member 5 and the sash 3 are formed with interfitting means, and one of these parts is formed with a groove or channel for receiving a tongueor rib on the other of the parts, and a U-shaped weather strip is located in the groove or channel for receiving the tongue of the guide.

- In the illustrated embodiment of my invention,

the guide is formed with the tongue or rib and the sash with the groove or channel 3 in the edge thereof in which the U-shaped weather strip is located.

Each guide member 5 is formed with a base from the intermediate portion of which the tongue or rib 9 extends, the base slidably engaging opposite sides of the channel 6 and being freely movable in a direction edgewise of the sash therein. 7

Iii designates a fibrous or non-metallic U- shaped weather strip in the groove or channel of the stile of the sash 3 and the rib extends between the sides of the U formation with the end of the rib coacting at II with the bottom or intermediate portion of the U-shaped strip.

Heretofore the guide members, as before pointed out, have either been hand adjusted in an edg'ewise direction relatively to the sash and then firmly clamped in their adjusted position,

or have been spring-pressed at spaced apart points, so that they act brake-shoe fashion or have been spring-pressed at spaced points, and after the adjusted position determined, firmly clamped in the adjusted position.

In this sash, the guide member is freely movable at all times but is pressed outwardly uniformly at all points throughout its length or a length at least equal to the height of the sash. when the sash is closed, so that the guide is pressed in an edgewise direction uniformly at all points throughout its length with an easy pressure, and the automatic adjusting action takes place at all times without the brake-shoe effect. The means for effecting this consists of a. resilient cushion l2 forming a backing for the guide member 5 and located between the base of the guide member 5 and the bottom of the channel Ii, the cushion being preferably'carried by the guide member as a unit therewith and usually cemented thereto, as at It. Preferably, the cushion i2 is a strip of soft sponge rubber extending throughout the height or length of the guide member 5. In the form seen in Figure 7, the

cushion member 50 is formed of a strip of rubber having lengthwise ribs or projections Si, 52 on opposite sides thereof, the projections or ribs on one side alternating with those on the other, the ribs being for the purpose of-making the strip easily resilient.

In order to relieve the U-shaped weather strip in of the thrust of the rib I, wear pieces or inserts of a harder material than the U-shaped weather strip are provided at spaced apart points in the groove of the sash and preferably near the upper and lower ends-of the sash, these wear pieces coacting with the edge of the rib or tongue 9. i4 and I5 designate respectively the wear strips or inserts, these being usually of bakelite or fiber with a rounding surface, the apex of which engages the end edge of the rib 9. The wear piece or insert I'd at the upper end of the sash extends transversely through the side walls of the channel or groove 3 with the ends in openings in said walls, and through the intermediate part of the U-shaped strip Ill. The ends are covered or held in position by the end portions I6 of the walls I! of the top rail of the sash, which are held assembled to the stile of the sash by the sleeve screws l8. Thus, the insert It holds the weather strip in from sliding relatively to the sash during raising and lowering of the sash. The lower wear piece or insert i5 is located above the bottom rail l9'of the sash, so as not to interfere with the sash holder mechanism includingthe latch bolt 20. This lower wear piece or insert is merely mounted in a transverse perforation 2| in the intermediate portion of the U-shaped weather strip. It is placed in the perforation 2| before the strip III is placed in the groove of the .stile of the sash. The weather strips II) are formed with a soft metal backing strip l0 stitched to the intermediate part of the U formation of the strip. The fiber portion only is cut out to form the perforations for the inserts l4, I5, so that the backing strips close the bottoms of the perforations for the inserts i4, i5. The latch bolts 20 coact with openings 20 in the bases of the guides 5.

In the structures shown in Figures 3 and 7, the post consists of a T-shaped body and the channel members 6 are located on opposite sides of the leg of the T formation and secured thereto in any suitable manner, as by sleeve screws 22. The screws 8, which secure the face plate I to the post structure, thread into plugs 23 which are applied to the leg of the T formation, these plugs having a bifurcated base 24, the branches of which are extended over the'si des of the leg of the T formation,

and are secured thereto, as by rivets 25. These branches 24 makeprojections on opposite sides of the leg of the T formation, and in order that the bottom of the channels 6 may thrust against the leg of the T formation, these bottoms are provided with lengthwise spacers or ribs 26 thrusting against the sides of the leg of the T formation, and these ribs are cut away, as seen in Figure 4, in order that the bottom of the channel 6 may span over the branches 24. The plugs are long enough to prevent the plate 1 from tightly clamping against the guide 5 and the rubber cushion l2 when the screws 5 are tightcried, in order that the guide 5 and cushion l2 may be freely slidable in the channel 5 to effect the automatic adjustment.

In Figure 8, the frame or post structure is shown as a pillar rectangular in general form in cross section to which the guide member is apchannel 50, this being secured in position by a screw 55 threading through the same and into the base 5|. In orderto make the sash weather tight, or tov guard against and prevent moisture and water from entering or beatinginto the 1 strip 66 has a lip 69 tensioned to press against the outer side of the stile of, the sash.

In Figure 8, the base of the guide channel is shown as formed convex and the cushion strip l2 as rectangular in cross section and normally engaging, if not under compression, only on the apex portion of the convex bottom of the channel, and when compressed, free to distort-into the spaces at the sides of the convex base portion or the spaces at the end of the arc of the convex portion. Owing to the convex formation of the base and the rectangular formation of the cushion i2, the. cushion it exerts a slow easy resiliency under pressure.

In operation, the guides 5 and their rubber backing can be placed with the tongues of the guides in juxtaposition in the weather strip of the sash, and then the sash and the .guides placed in the channels 6 and the face plate I applied. During raising and lowering of the sash, if there are any misalinements out of the vertical in the post structure, the rubber backing or cushion compensates for such misalinements, and also presses the guide 5 to its full extent in an edgewise direcoccur in the widths of standard sashes or window openings.

The variations are usually due to fitting the window frames to the window openings.

If there is any misalinement,- the cushion permits the guide member to slide in and out, but as the re-action of the rubber cushion is very light and evenly distributed, the pressure is not localized or applied with a binding or braking effect at any point, and the guide is not pressed with a brakeshoe effect against the sash, and yet the guide always has a compensating movement. The inserts it, l5 relieve the weather strip ill of wear at the edge of the rib or tongue, allowing merely a touching contact between the end of the rib or tongue and the weather strip, and these inserts further contribute toward eliminating or avoiding the brake-shoe action.
